AXLE-BOX.

P-CIFICATION forming part of Letters Patent No. 348,432, dated August 31, 1886.

Application filed J une 10, 1886. Serial New-1,766.

To all whom it may concern Be it known that I, LoUis SWATERS VAN SCHAUMBURG, a subject of the King of Prus- Sia, residing at Bochum, in the Kingdom of Prussia, Germany, have invented new and useful Improvements in Axle-Boxes, of which the following is a specification.

This invention has for its object to provide a novel axle and wheel-hub for vehicles; and

1o it consists in the features of construction and combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, in whichi Figure l represents a longitudinal central section of an axle-box embodying my invention. Fig. l is a transverse section thereof in the plane A I3, Fig. 1. Fig. l" is a section in the plane C I), Fig. l. Fig. 2is a long`1- tndinal central section of amodilication. Fig.

2o 2 is a longitudinal central section of a modification. Fig. 2SL is a transverse section thereof in the plane E F, Fig. 2. Fig. Sis alougitudinal section of another modification. Fig. 3 is a transverse section in the plane G H, Fig. 3.

Similar letters indicate corresponding parts. In the drawings, the letter a designates the axle, which is annularly recessed at the proper intervals to receive shaftless rolls k, that are tted in circular recesses in a bush, b, which 3o consists of one piece of metal. This bush b is rigidly secured to the hub of the wheel, and as shown in Figsl and l, by means of screws c, which are screwed up so as to lie both in the hub and in the bush, whereby these parts are very securely held. As shown in Figs. 2 and 2, the bush is secured to the hub by the projecting lugs d of a ring, m, which ring is attached to the bush by screws c, as before; or, as shown in Fig. 3, they may be joined very 4o securely by means of a screw, j', which is screwed up in the bush and prevented from working loose by an interposed washer which is fitted in a square hole of the bush.

'Io prevent dust and dirt from entering the bush, plates 7L fi are secured by screws over its two ends, one plate being open to receive the axle.

To insert the shaftless rolls 7.: into the bush, I provide openings o, which are subsequently 5o closed by conical plugs provided with dovetail slides Z, Figs. l, 1", and l, o1' by the ring m,

previously described, Figs. 2 and 2f. The rollers l.: are properly designed to entirely :fill up the circular recesses in thebush Z, so that the axle is entirely surrounded by and supported upon these circular vseries of rollers, and consequently very little friction is produced, since the rollers are shaftless. The end walls of the annular recesses in the axle andin the bush serve to prevent longitudinal displacement of the rolls, since portions of each end ofthe rolls bear, respectively, against the end walls formed by the annular recesses in the axle and the bush. By this means I avoid using cage-rings in which the ends of the rollers are journaled. 6 5

Tolubricatc the rollers and the axle both the axle and bush have a circular recess inter1nediate of the two sets of rollers 7U', which recesses form an annular lubrieating-chamber, into which a solid lubricant is pressed through 7o a hole or channel, a, extending from the end of the axle and into the lubricating-chamber. This feed hole or channel can be closed by a plug or screw, p, screwed in the end of the axle. The lubricatiiig-chamber comlnunicates with both sets of rollers through annularspaces between the axle and thebush, which are formed by making the diameter of the same smaller at these points than the internal diameter of the bush, so that the lubricant can readily flow 8o to the rollers.

The object of my invention is to do away with the use of washers, screw-plugs, and nuts and the caps and linehpins commonly employed in the construction of axle boxes, which have proved very unreliable.

IIeretofore a metallic hub has been provided with internal flanges containing between them a series of rollers separately j ournaled at their ends to cagerings, the axle bearing only on 9o the rollers. Such construction does not constitute my invention, and is not claimed by me.

NVhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a wheel-hub, ofa bushing, b, inserted and held therein, and provided adjacent to cach end with a circular recess,and intermediate said recesscshaving the annular lubricating-chamber g, the axle a, having adjacent to each end an annular recess, 10a and provided with the lubricating-channela, extending through the axle from its outer end IZY tion with the said intermediate lubricatingchamber,and shaftlcss rolls 7c, arrangedin the recesses of the axle and bush, said lubricating-chamber being in communication with the respective recesses in the axle and bush to lubricate the rolls, substantially as and for the purposes described.

In testimony whereof Ihave signed my name to this specification in the presen ce of two subscribing Witnesses. f
